The circulation around Tropical Storm Lee affected southeast Louisiana from late on September 2nd through September 4 with primarily onshore southeast and south wind flow. Tropical Storm Lee eventually weakened over inland areas later on September 4th and existed the region on September 5th. The slow forward speed and broad circulation caused above normal tides along the southeast Louisiana and south Mississippi coast and tidal Lakes of Pontchartrain and Maurepas. Tides were generally 2 to 5 feet above normal. Higher gage readings included 6.25 ft NAVD at the Seabrook Bridge at Lake Pontchartain, 5.40 ft MLLW at Shell Beach, St Bernard Parish; 5.28 ft NAVD at Mandeville, and 4.22 ft NAVD at Golden Meadow, Lafourche Parish.
Storm surge flooding was primarily confined to areas near the coast and tidal lakes, and outside of hurricane protection levees. Low lying roadways were flooded in many areas. The areas with the greatest impact to houses and other structures included; Jefferson Parish with approximately 105 homes experiencing minor flooding in the Lafitte area; Livingston Parish with approximately 250 homes having minor flooding; St Tammany Parish with approximately 60 house with minor flooding.
